Liquid crystal panel

Abstract

A coil (14) is formed by winding a part of a counter signal line (13) within a surface in parallel to a substrate, at the time of arranging the counter signal line (13) electrically connected to a counter electrode (24) on an active matrix substrate (11). A double-layer wiring layer provided on the active matrix substrate (11) is used for forming the coil (14). High frequency noise on a counter electrode voltage is suppressed by inserting the coil (14) into the counter signal line (13) in series, and display qualities of a liquid crystal screen is improved by stabilizing a voltage applied to a liquid crystal. An equivalent coil may be formed using a power source line on the active matrix substrate (11). Thus, a liquid crystal panel strong against noise is provided without providing a noise countermeasure component.

Description

technical field [0001] The present invention relates to liquid crystal panels used in display units of various electronic devices. Background technique [0002] For electronic equipment, in terms of electrical noise, it is required that the noise emitted by itself is small and will not have a bad influence on other equipment, and that even if it receives a certain degree of noise from other equipment, it will not cause malfunction (EMC: Electron) -Magnetic Compatibility, electromagnetic compatibility). In addition, in electronic devices performing wireless communication or electronic devices operating at high speed (such as mobile phones), even if noise emitted by other devices is blocked, the noise emitted by itself will adversely affect the performance of the device. [0003] For example, in Figure 5 In the illustrated foldable mobile phone, a liquid crystal module 83 is housed in a cover case 81 , and a CPU 84 , a logic circuit 85 , a high frequency circuit 86 , a commu...

Problems solved by technology

Once noise is superimposed on this wiring, noise will also be superimposed on the opposite electrode voltage of the liquid crystal panel via the liquid crystal module control circuit, and the voltage applied to the liquid crystal becomes unstable, resulting in a decrease in the display quality of the liquid crystal screen.
